[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation method for smoothly and safely crushing and removing stools from patients with dysfecation using a defecation treatment device.

[0002]

2. Description of the Related Art As the population ages, the number of bedridden elderly people is increasing. In addition, there are many people with physical disabilities due to traffic accidents and congenital factors, and about half of them are accompanied by nerve palsy. For these people, although the treatment of defecation is one of the major problems in daily life, only a urine collection device has been developed as a defecation device, and a laxative and an enema still remain for fecal defecation treatment. Alternatively, a method of urging defecation such as excretion is adopted. Particularly, for patients who have a hard stool with difficult symptoms of defecation, a means of forcible excretion is combined with a combination of treatments such as high-pressure enema, defecation, and suppositories, but these treatments are physical to the patient. In addition to giving a great deal of psychological distress, the defecation caregiver must be engaged in defecation work for a long time, and is obliged to perform a disgusting work that must endure the odor of feces.

As means for solving such various problems in defecation treatment, the present inventors have already developed a large number of excretion treatment devices which efficiently crush and remove feces in the rectum by utilizing mechanical vibration. Developed and proposed (JP-A-1-1985)

Japanese Patent Application Laid-Open No. 3-151981, Japanese Patent Application No. 3-15851, etc.).

Of these, the defecation treatment device of Japanese Patent Application No. 3-15851 has a mechanism for controlling the drive unit by utilizing the pressure signals on the enema fluid supply side and the stool crushing / sucking side. The pressure inside the rectum that fluctuates during the process can always be automatically adjusted to an appropriate range. That is, as shown in FIG. 2, the basic constitution of the defecation treatment apparatus is such that the irrigation side inserts enema fluid from an enema fluid container 2 through an irrigation pump 3 and a heat exchanger 4 into an insertion tool 1 having a horn built into the distal end. The irrigation chamber 6 through the irrigation tube 5
From the suction chamber 7 through the suction pipe 7 to the storage container 12 that is connected via the exhaust pipe 11 equipped with the suction pump 9 and the pressure regulating valve 10 on the suction side. For the pressure control, a mechanism for capturing the internal pressures of the irrigation chamber 6 and the suction chamber 8 with the pressure sensor 13 and transmitting the pressure to the control unit 14 and giving an operation / stop command to the drive unit 15 within a preset pressure range, Has become. Further, the branch pipe 16 connecting the irrigation pipe 5 and the suction pipe 7 is
When the clogging occurs, the pinch valve 17 is interlocked to allow the intestinal fluid to flow into this route, and is installed to remove the clogging through the suction pipe 7.

[0005]

However, in the defecation processing device having the above mechanism, the pressure regulating valve is used for controlling the suction pressure.
Since 10 is used, opening this means that the suction route side is open to the atmosphere, so there is a difference in pressure due to the difference in the installation positions of the insertion tool 1 and the suction chamber 8, and accurate internal pressure detection becomes impossible. Sometimes. When such a situation occurs, the control balance is disturbed, and when the amount of suction is relatively small with respect to the amount of enema fluid to be supplied, the enema fluid may accumulate in the rectum and the patient may experience phenomena such as water intoxication. Cause to cause.

An object of the present invention is to solve the above problems and provide a method for operating a defecation treatment device which can always treat safely with a well-balanced control when using a defecation treatment device equipped with a pressure control mechanism. Where it is.

[0007]

In order to achieve the above object, a method of operating a defecation treatment apparatus according to the present invention is an insertion of enema fluid irrigation means and crushed feces suction means having a horn that produces mechanical vibration. An excretion treatment device equipped with a control mechanism for transmitting an operation / stop control signal to an irrigation pump, a suction pump, and a drive unit of a vibration source by a sensor signal which detects the internal pressures of the irrigation side and the suction side, which are connected to a tool. Use, in inserting the insertion tool into the rectum from the anus to excrete and remove feces, measure the total amount of enema solution sent from the irrigation pump after the start of operation and the total amount of aspirates sucked and discharged from the suction pump, The structural feature is that pressure control, flow rate control, or treatment discontinuation is performed based on the total amount difference.

[0008]

In the defecation treatment device used in the present invention, the pressure sensor installed in the system captures the internal pressure state on the irrigation side and the suction side, and the control unit receiving the signal detects the overpressure exceeding the preset pressure range. Occasionally, the irrigation pump and the vibration drive unit are automatically stopped, and at the same time, the suction pump is operated to suck and remove feces to lower the internal pressure of the rectum. On the other hand, when the pressure is lower than the set pressure range, the suction pump is stopped, and the irrigation pump operates to increase the rectal internal pressure, and at the same time, the vibration drive unit is operated to vibrate the horn.

The present invention, combined with the automatic control mechanism inherent in the above-mentioned apparatus, includes the total amount of enema fluid that is fed into the rectum after the start of the operation of defecation treatment, and the crushed feces and the infusion that are aspirated during the treatment stage. The total amount of intestinal fluid is measured, and based on the difference in the total amount, the operator is characterized by an operation method of automatically or manually controlling the pressure or the flow rate or stopping the process based on a value preset by the operator. A safer and smoother defecation process can be performed through device control and operation control.

EXAMPLES The present invention will be described in detail below based on examples. FIG. 1 is an overall configuration diagram showing a defecation treatment apparatus suitable for the operation of the present invention. The piping line on the irrigation side is connected to the irrigation nipple of the insertion tool 1 by the irrigation pipe 5 from the enema solution container 2 through the heat exchanger 4, the irrigation pump 3, and the irrigation chamber 6. On the other hand, the piping line on the suction side enters the storage container 12 to which the exhaust pipe 11 is connected from the insertion tool 1 through the suction pipe 7 and the suction pump 9.

Therefore, in this structure, the pressure regulating valve which causes the accurate pressure detection in the conventional apparatus shown in FIG.
No equipment corresponding to 10 and the branch pipe 16 that complicates the circuit system is installed. However, it is preferable to use a roller pump having the same mechanism as the irrigation pump 3 for the suction pump 9. The reason for this is that, unlike a piston type pump, etc., a roller pump is a mechanism that sucks while squeezing a tube so that a certain amount can always be reliably sucked in. Also, a phenomenon such as drawing of suctioned matter into the pump, oil leakage, etc. This is because there is no occurrence. Although the suction pump 9 is installed between the insert 1 and the storage container 12 in FIG.
It may be attached to the exhaust pipe 11 of the storage container 12. However, in this case, since the suction is performed including the storage container 12, it is necessary to reduce the size of the storage container 12 or increase the pump rotation speed in advance.

Irrigation pipe 6 constituting a piping line
As the material of the suction pipe 7, for example, soft polyvinyl chloride, silicone resin, neoprene rubber, butyl rubber, fluorine rubber, etc. can be mentioned, but preferably a transparent resin whose contents can be observed and having a restoring force. Formed by. The type of material for the irrigation chamber 6 is not limited as long as it is a transparent hollow container shape whose contents can be observed. Further, the storage container 12 is made of a transparent resin material having a bottle shape and having a strength capable of withstanding a reduced pressure.

In FIG. 1, the route shown by the broken line is the sensing line, and the route shown by the alternate long and short dash line is the control signal line. In the control system of the pressure system, the irrigation chamber 6 and the suction pipe 7 are connected to the sensor unit 19, and the signal captured by the pressure sensor is irrigated within the pressure range preset by the control function of the control unit 14. A control signal for operating / stopping is transmitted to a driving unit 15 of a vibration source that vibrates the pump 3, the suction pump 9 and the insertion tool 1. As a pressure sensor to be installed, -400mmHg ~
It can be measured in the range of 400mmHg, and either gauge type or differential pressure type can be used. However, it is preferable to use a differential pressure type that can measure both positive and negative pressures with reference to atmospheric pressure.

The control system of the temperature system is for adjusting the temperature of the enema fluid to a temperature suitable for injecting it into the body. The control signal having an appropriate temperature is converted and transmitted to the heat exchanger 4. The temperature sensor may be of any type as long as it has a function of converting temperature into an electric signal, but a small one such as a thermistor or a thermocouple is suitable for the purpose of the present invention.

The control of the heat exchanger 4 is, for example, ON-OFF.
It can be configured by control, PID control, PWM control, fuzzy control, or the like. The heat exchanger 4 has a function of controlling the temperature of heating the enema fluid, and the shape of the heater is not limited, but it is preferable that the heater can instantly heat the heat.

During the defecation process, the enema fluid is adjusted to an appropriate temperature by the heat exchanger 4 and then injected into the rectum from the distal end of the insertion tool 1 through the irrigation chamber 6 by the irrigation pump 3. Then, the drive unit 15 is operated to apply ultrasonic vibration to the horn 2 of the insertion tool 1. At this time, the pressure in the irrigation chamber 6 is detected by the pressure sensor, and when the detected pressure exceeds the upper limit of the preset pressure range, the irrigation pump 3 and the drive unit are controlled by the control signal from the control unit 14. 15 stops, and at the same time, the suction pump 9 operates to start suction removal, thereby decreasing the rectal pressure.

In the suction stage, the suction pump 9 is operated to store the crushed feces and the enema fluid in the rectum 12
Collect by suction. At this time, the internal pressure of the suction pipe 7 is detected by the pressure sensor, and when the detected pressure falls below the lower limit of the set pressure, the control signal from the control unit 14 stops the suction pump 9 and, at the same time, the drive unit 15 and the irrigation pump 3 Is operated to supply enema fluid, and the rectal pressure is raised to an appropriate range. In particular, since damage to the rectum negative pressure strong during suction, the suction pressure is necessary to keep the following -1mH ₂ O.

During these processes, the apparatus automatically measures the total amount of enema fluid fed from the irrigation pump 3 and the total amount of aspirated substances sucked and discharged by the suction pump 9. The total amount of enema fluid is integrated from a driving source such as the rotation speed of the irrigation pump 3, driving voltage or current, or measured by attaching an electronic flow meter to the irrigation tube 5. On the other hand, for the total amount of aspirate, measure the amount of crushed feces and enema collected in the storage container 12 with a measuring device such as an electronic balance, or attach an electronic flow meter to the suction pipe 7. measure.

While observing the difference between the total amount of enema fluid and the total amount of aspirated substance which is automatically measured and displayed, the operator adjusts the rotation speed of the roller pump so that the difference does not become large, or the preset value is set to 1 Pressure control and total amount control are performed by changing the time settings for enema, ultrasonic vibration, and suction operation during the cycle. If suction becomes impossible for some reason, the total volume difference becomes large, but if the total volume difference exceeds a preset value, the intestinal cleansing fluid may have risen to the digestive tract above the rectum. However, the recovery is impossible and the treatment must be stopped. Therefore, when the clogging occurs, it is necessary to remove the clogging by taking out the suction pump 9 and rotating the suction pump 9 in the reverse direction. The predetermined set value is preferably about 0.5 to 1 liter which does not cause water poisoning, and the device automatically stops when the set value is exceeded.

By operating such a defecation treatment device, defecation treatment can be performed extremely safely and smoothly.

[0021]

As described above, according to the method for operating the defecation treatment apparatus according to the present invention, the rectal internal pressure fluctuating during the irrigation and the suction stage during the defecation treatment can be accurately controlled within an appropriate range, and the rectum can be controlled. Since a large amount of enema fluid does not remain inside, the rectal damage, the pain and discomfort experienced by the patient are eliminated, and the risk of water poisoning is eliminated. Therefore, solid feces can be excreted safely at all times.
